Used Car Buyer Checklist: Code 401
Check the door panel switches. A seat heating icon accompanied by a blue fan icon confirms climatisation hardware. Test for proper airflow; fans can accumulate dust or wear out, resulting in noisy operation.
🚨 Avoid Retrofit Frauds:Always decode the VIN configuration rather than relying on visual trims. Sellers frequently install visual replicas (such as speaker covers or AMG body panels) on standard vehicles to charge a premium. A genuine datacard decode matches the vehicle's manufacturing specifications on the day it rolled off the assembly line.
